The fit on Brooks shirts and apparel is hit or miss. A small, fitted jacket should be snug on me, but Brooks apparel is often a little larger or loose. Becuase of this I ordered an extra small, and after washing it fit very well and snug, though the sleeves were just a little short. Overall, its a nice, stylish jacket to wear outdoors (40-60F), and should be good to jog in above 30F. Definitely recommend for at lease a nice track jacket to wear out and about.

This is a sharp jacket and you will be noticed. I wear it to work, gym and before/after runs. I purchased the black/white jacket and it matches the Spartan II pants and Vapor Dry 3D Stadium Pant nicely. I normally wear small and purchased a small. It is slightly tighter than other jackets, but fits fine and can run comfortably. If you're looking for a jacket to layer with, order the next size.
